Many people think that bitcoin should move up in a straight line but this is not how the market works. Markets may show us many up and down before moving up and sadly people are not ready for these movements and sell their bitcoin before it reaches the all time high.
The trading strategy in your photo looks almost identical.
The reality is more difficult, you know. people just want to do one-way trading, they always think upwards. As soon as there is a slight correction in the market, they get upset and leave the market in fear. This type of behavior is seen only among online traders, real hodlers are never disturbed/upset during the correction period, they just take the opportunity to buy more in the dip.
You have to grow up with bitcoin. Most of the people that I know who had bitcoins in the early days made this mistake of chasing profits and selling everything at first high or first low. Then they kept observing how it moves and understood their mistakes. Some needed a few months to buy back, some a few years but they eventually came back and held for a long time, ignoring the short-term volatility.
Once you've been through a full bull-bear cycle you become immune to hype and panic.
